formed of Vsheet, metal walls, forrning chan# y `11116.58 received over the ,hrad'dgeiid jffthe f i' `holt being received in a recess'e` at the'cther' p side-bar 21, and has an arm 62 iixed thereto, this arm being articulated at 63 with the link 55, the arm andthe link forming a toggle link structure rbetween the seat-frame :and

said block. A handle-arm 65 is also fixed to the rocker-pin, and has a handle 66 thereon. When the handle is moved upwardly, the

block is propelled rearwardly, for relievingv clamping action on the outer portion of the window-sill. When the operating armis` moved downwardly, the. toggle-link is oper- Y I ated to force the block toward the windowsill. l `When the block is in clamped relation,

` the axis ofthe articulation 63 has passed a Aright line between the axes of the articulations 56, 61, for locking the toggle-links and preventing retraction ofthe blocks by rearward pressure upon thefblocks. When the .toggle-links are in this relation, the toggle` link 55 restsupon the lower wall of the recess 57 for limiting downward movement of the toggle-links. Y

A back 71 ispivoted to the seat-frame, for instance, on` pivot-pins 72, in bearings 73, 74,

respectively on the rear 'ends'of the sidebars 11 ofthe seat-frame and the lower ends r,of side-bars 75 of said back. A cross-wall 76 side-bars being exemplified as channelbars.

The back may be provided-with a covering V7 8, for instance of canvas, held to the crosswall of the back by lacings 79.

,A-covering 81 is also preferably provided for the seat, laced at its respective front and rear ends .to said seat by lacings 82.

iOf

vUpright bars 85 extend upwardly froml the seat-frame, and are preferably pivoted to said seat-frame on pins 86, which are received through the lower ends of said upf right bars and upwardextensions 87 of the Y extension 93 of theside-strap k26, the shank` fhaving a wing handle 94Ek at one end and a laterally extending lug 95 at its other end.

side-'straps 25. There is one of these upright bars at each `side of the seat. A link 88 at each 'side of the seat connects the upright bar with the seat-frame,jbeing articulated fwithfthe upright bar at 89 and with the seat-frame at 90. c v Y The latter articulation is preferably releasable, and may comprise for instance a shank 91 pivoted in a hole 92 in an upward `The lower end of the link is provided with a h'ole96, from which a slot 97 extends. The

lug is arranged lto be received through the slot, whereupon the` shank is turned for placing its lug across the wall of the hole, for holding the link in place.

A link 101 connects the upright bar with l I the back, preferably lby articulations at 102,

103. One of these articulations, exemplified as the articulation 102, may be releasable, and

be an articulation similar to the articulation Flexible connections, shown as ychains 105, have their respective ends secured to the link 101 and the seat-frame` at each side of the seat. f

Thev construct-ion of upright bars,vlinks and flexible connections form sides for the seat, and' hold the back securely in place when the device is vin use, and are so arranged as to permit collapsingof theback land of the sides for convenient and compact V112 with the sidebars of the back. The

front ends of the flexible connections are provided with hooks 1.13, received throughV eyes 114 in eye-plates 115 secured'to the side walls 116 of the window framing. The hooks are spring-latch hooks ofusual construction.

I have in Figs. 8 and 9 shown a modication for the block securing meansQin which the blocks have'lbolts'121 extending therefrom, the heads 'of thevboltsfbeing non-rotatively located in the blocks, and the threaded ends thereof extending through slots 122 in the outer 'wall ofthe guidewayx51, wing-nuts 123 being threaded over the boltsand clamping'the blocks in Vplace in cooperative relation with the window sill, or inI released po siti'on.

The' seat-frame may be* provided with `pads 125 for restingon the inner portion of the window-sill.

Means may also be provided for positionin g the seat-frame between the sides of they window opening, yas by vproviding the same,

preferably ate'ach side ofthe seat vfrarne,

with a spacing block`127, pivoted to la 'lug .128 on the side-bar 11 by a pin 129, the heel 130 ofthe block beingarrangedto bear compressingly upon the side wall 116 when the spacing block is in extended position between the side-bar and the side wall 116of the window opening. lVhen either or' both of these spacing blocks are not in use they may be swung lengthwise alongside the sidebars. rSpacing blocks of different sizes Vmay be used for 'window--openings'of different l widths.

y When the device is notin use, the'upright bars and links and back of the window-seat maybe arranged lengthwisev with relation to the seat, and the aprons and flexible connections laid upon the back, for form-ing a compact structure and taking up little room.

VSuch lrelation of the parts is exemplified in Figs. 5 and 6, in which the releasable connections 90, 102, are released for swinging the back forwardly so as to bearranged substantially parallel with the seat. The links 88 and the upright bars are collapsed for lying alongside the seat-frame, and the links lOl are arranged alongside the back.

The flexible connections 105v and lllare laid upon the back, and the aprons are laidupon the flexible connections. Y

My improved device may be compactly arranged for carriage and for storage; it is strong and durable, and is readily fattached to the window-sill.V vThe frame parts, and the seat and back are'` preferably vmade of metal, sheet andbar metal being employed' f for the purpose of economical construction.`

Having thus fullydescribed my invention, what I claimv as new, and desire to secure by Letters Patent, is: A' j 1. In a device of the character' described,

the 'combination of a seat-frame `provided with a yoke at its rear end, a seat in said seat-frame, means for releasably securing said seat-frame to a window-sill, a back the lower end of which is located between and' pivoted to the rear ends ofthe sidesof said yoke, an upwardly extending upright bar at the middle of each side of said seat-frame,

eachiof said upright bars pivoted at-itsy l lower end to the middle portion of one side of said seat-frame, a linkl for each of vsaid upright bars having pivotal connection at its front end with the upper end of its upright bar and extending upwardly and rearwardly and having pivotal connection at its rear end with thel upper end Vof said back, a downrwardly and forwardly extending link-brace at each side-of said seat-frame, eachof said link-braces having its rear endpivoted to the middle portionI of one of said upright bars, the front, end of each ofV said linK- braces provided with a releasable articulation with one of thesides of said seat-frame, whereby upon` release of said last-named articulation said link-.brace and saidupright bar are moved forwardly into parallelism with each other and with 'saidseat-frame, and said back is arranged `to be swung Vforwardly into parallelism with said seat-framel betweenl said sides of said yoke of said sea-tframe, and 'flexible means between said firstnamed linka-nd said seat-frame forming side f walls for said seat.'
